Problems solved by technology

[0003] The object of the present invention is to provide a device and method for detecting liquid leakage on the surface of a liquid crystal screen. The upper surface of the liquid crystal screen is adsorbed by a silica gel suction cup, and a certain suction force is applied. If the liquid crystal screen leaks, it can be known through the numerical change of the pressure sensor. There are tiny gaps, damage or weakness on the surface, there is no obvious leakage, but there has been a slight leakage or a great risk of leakage, and the location of the leakage can be accurately determined according to the position of multiple rods or detection units to prevent the liquid from directly leaking. Environmental pollution caused by external leakage, to solve the problems raised in the above-mentioned background technology

Abstract

The invention discloses a liquid crystal screen surface liquid leakage detection device and method, and belongs to the technical field of liquid leakage detection. The liquid crystal screen surface liquid leakage detection device comprises a base, a table top, a fixing mechanism, a lifting mechanism, a side bracket and an air pressure detection mechanism, the four corners of the upper end of the base are fixedly connected with an annular table top through bolts, the fixing mechanism is slidably connected in a middle empty groove of the table top, and the upper surface of the fixing mechanism is provided with a gravity sensor. Silica gel suckers adsorb the upper surface of a liquid crystal screen; certain suction force is applied, if the liquid crystal screen leaks, the leakage can be knownthrough the value change of a pressure sensor; aiming at the conditions that tiny gaps, damaged or weak parts on the surface of the liquid crystal screen do not have obvious leakage, but have micro leakage or have great leakage risks, the leakage position can be accurately determined according to the positions of a plurality of rod bodies or detection units, and environmental pollution caused bydirect leakage of liquid outside is prevented.

Description

technical field [0001] The invention relates to the technical field of liquid leakage detection, in particular to a liquid leakage detection device and method on the surface of a liquid crystal screen. Background technique [0002] A liquid crystal display (LCD) is a type of display used in digital timepieces and many portable computers. The LCD display uses two sheets of polarized material with a liquid crystal solution between them. When an electric current is passed through this liquid, it rearranges the crystals so that light cannot pass through them. However, the liquid crystal display is fragile, and it is easy to crack due to impact during production, transportation and use, resulting in the leakage of liquid crystal solution. There are no obvious leaks in tiny gaps, damages or weak places, but there are micro leaks or there is a great risk of leakage, which cannot be visually observed with the naked eye. The device does not specifically detect small damages on the...
